what's up crew

well the rock is back up and running need advice on super charging verse turbo I'm ready to do on or the other which one would be best.

off the line and also in the long run.

 

do you have 4-6 grand? turbo's and superchargers are not only expensive to buy, but expensive to install if you have someone else do it.

turbos: not gonna happen unless you have someone custom build you one

supercharger: ati makes a DAMN good s/c ... if you forge out the internals, and build your engine for a s/c, you can probably get about 90-100% of your power.... meaning a 300 hp monster turns into a 600 hp beast...

turbos, you have to worry about turbo lag... but once you reach boost, you're pretty str8... with superchargers, you have boost all the way down the rpms, but it starts off low and then goes to max boost at the end of the rpm. ex: 3000 rpm, 2# boost, 4000 rpm, 4#, 5000 rpm 6#, and so on till you reach the end of your rpm range and the end of your boost... my money's on the supercharger if you want me to be honest with you... you ALWAYS have power no matter what, if you slam on the gas, you're gonna have boost... even if it's 2# or whatever if your at a low rpm... you have to wait for your turbo to spool up if you slam on the gas... it might cost you the race

 

off the line and in the long run? The supercharger is probably a better buy...The turbo will probably cost more after installation and like djhaf said, the supercharger is always gonna give you the power you need. Just my two cents

 

Not based on ANYTHING the above fellas mentioned, but I suggest a supercharger only for the fact that they are avaliable in kit form and for a much better price. A turbo setup would require more research, ordering of specific parts, fabrication of plumbing, engineering of where everything goes and hopefully in the end it all work as planned. I'd do the ATI Procharger D-1 Kit and pulley it for 8-10PSI. Looks great, works great, good reputation, and it'll allow a stock motor to make good power and be able to make boost after adding cubic inches, better top end parts, etc.. Goodluck!

As far as turbo lag and losing races because of it, you sir obviously have not been in a properly tuned/setup turbo car. Even huge turbos on a tiny V6 spool extremely fast if tuned right. A black 274 cube GN known to this board has twin 60MM turbos on it running well into the 8's and he has full boost off the line within .7 seconds. Lag? And that's full boost well before the middle of 1st gear even. A blower needs to wind first gear all the way out to achieve full boost. What takes longer? A couple tenths of a second to achieve full boost from a turbo or winding out first gear for it? How long does first gear take to go by? 1 second? 3? 5? car pending of course but it's possible some people see my point.

 

We all know turbos make more power....it's having the money to pay someone to fabricate a custom setup correctly.

SC's have alot of kits out, simplicity and streetability.

 

Depends on what you want to do and how much you want to spend.

Do you want to drag race or road race?

A supercharger or blower is more suited to drag racing. Turbo's are more suited to road racing.

A supercharger creates parasitic drag from being belt driven and will use up to 20% of your engines power just to turn it but is instant because it is belt driven. Therefor there is no noticeable lag.


Twin, sequintial turbos will help to reduce lag. If you have one small turbo driven off one bank and a large primary driven from the other bank, lag is almost not noticed, especially if you use ball bearing turbos.

If you are on a budget and primarily drag race, go with a supercharger.

Either way you go, use a good sized intercooler and spray nitrous or carbon dioxide on the intercooler to get the temps of the intercooler way below ambient. It's a cheap and easy way to get lower intake air temps from a blown engine.

 

Doesn't Gale Banks make a turbo kit? You would need an intercooler if you want to make a turbo really work because of the high heat of the air coming out of the turbo. SC is much cooler and thus less plumbing.

 

If youve got the time, and money Turbo is the way to go. They are more efficient than superchargers, and much easier to regulate boost. And as far as lag is concerned thats mostly for small displacement engines to put up with. With a large V-8, your spitting out enough exhaust gas, that even with a large single turbo, lag really isnt a factor at all if you have it set-up right.
But you will most likely need alot mroe fabrication with a turbo kit.

 

Heh just the idea of that makes me giddy id love to run a setup like that in a camaro....on the other hand i cant afford it and would probably kill my self in it this is the ultimate way to go for a true performance car. No better way

 

well thanks for the reply my dad is also a turbo head he's going to do the install so that';s not an issue. i got 3000 as of right now what's another two months of waiting on money if it's going to be faster. I like vortech supercharger they said i'd be pushing 450 with my set up which would be nice.

 

go procharger if your going to go s/c.... they're better than vortech's and they're not that big of a bitch to install like vortech's are

 

There should not be any noticeable lag with the turbo's on a V8, unless you're going for 1600 hp on a drag setup. I see full boost at 2000 rpms.

 

i'll correct myself then... i've noticed turbo lag on 4 cyl cars before, but the only v8 turbocharged car i've been in, i really didnt pay attention to see if there was lag... guess cuz i didnt notice it.

 

I love a good turbo/supercharger thread!! It's split pretty much in half as far as opinions. But I here's my .2

Supercharger- instant power (if not at "off idle", maybe 1100-1300rpm), dependability, more than enough companies that make camaro kits even for 4bbl. carbs,

Turbos- Lag "is" a factor, twin setup is recommended, custom fabrication might cost an arm&leg, running over 8psi might melt your mill if not tuned right, But....... Turbos do make good power when tuned right, would be perfect power adder for V6 4th Gen if there were'nt space issues,

Actually I want to run a twin turbo setup on my 305 (yea 305) and it has been done:

or a TT on my 2000 V6, just until I get my LS1 lol!!! and TT that out!!!

This idea has been done to death but you guys obviously have'nt been keeping up with the hotrod magz. This year alone super chevy has covered a 1990 Corvette twin turbo, a 1969 SS camaro Twin trubo and a few others. The Vette had problems with clearance of the huge pipes and the intercooler but it's a DAILY DRIVER so is the 69 SS!!! But main thing... The vette owner said money can get you 3 turbos installed if you wanted, keyword "Money". If yall really want I can scan the articles and post em up on my page.

 

Lag is a none issue when setup right. I have no problems with lag with my PT51 and a V6. Its especially a none issue on a V8.

And seriously, who needs a twin turbo setup on a V8? Single turbo cars are running in the 7's. A pretty mild combination can get into the 10's fairly easily. Anything faster than that shouldn't be on the street.

SC will put undo stress on any engine because its always turning. Turbo is there only when you need it. Build two engines side by side with the exact parts and bolt a SC on one and turbo on the other. See which is faster and lasts longer...turbo will come out on top.

My 2 pennies thrown in and IMHO
